Chapter 1: Introduction
Trimar-AP is an IEEE-802.11a|g|b compliant, maximum data rate of 54Mbps, full
functional wireless Access Point, which provides seamless incorporation of a wireless
network into an existing wired LAN infrastructure. Existing wired-network resources
such as DHCP, VPN, firewall, etc., reach across the Trimar-AP to the wireless client
workstations with total transparency. Trimar-AP wirelessly incorporatesa group of
workstations or other kinds of devices with wireless connectivity into a wired network—
just like a hub and switch.
Trimar-AP can be used wherever an 802.11 wireless LAN AP is appropriate. The
portable, compact form-factor of Trimar-AP, in conjunction with its non-intrusive nature,
makes it ideal for quick deployment of wireless network at events that involve rapid
setup: temporary offices, trade-shows, meetings, temporary POS, etc. There is no need
to request an IP address for the AP ahead of the time for it to perform its networking
functions. There is no worry about functionality conflicts with the incumbent network
setup when traveling to a temporary event. Traveling businessmen can also carry this
portable AP on the road to gain mobility in hotels.
In addition to higher speed, the Trimar-AP AP fully supports the current wireless
security standard in force. The Trimar-AP AP supports the 64 and 128-bit WEP
encryption and WPA –Wi-Fi Protected Access. WPA offers unprecedented wireless
security including both access control with 802.1X and communications confidentiality
with dynamic TKIP encryption. Please contact OTC for tutorial material on WPA.
Trimar-AP may interoperate with any WPA-compliant station radios, including OTC’s
ACR-201-G, and their attached workstation.
Trimar-AP also offers MAC-address-based access control. This access control used in
conjunction with the WPA for data encryption provides the highest degree of security for
the wireless network.
Trimar-AP includes a built-in Web server providing a web-based administration utility to
configure, monitor, and manage the radio. The network operator can access the Trimar-
AP from any immediate or remote host with a Web browser on the connected network.
Once the Trimar-AP is properly configured to match up with your wireless network, the
radio runs self-sufficiently without the aid of any driver program or connected Web
browser.

Chapter 2: Product Installation and Basic Operation
2.1 Safety Statements
Use only the power adapter provided with this product or other OTC authorized
replacement power adapter. Connect the power adapter to a properly grounded
electrical outlet that is near the product and easily accessible.
Refer service or repairs, other than those described in the user documentation, to a
professional service person.
2.2 Installing the Hardware
2.2.1 Power
Power is supplied to the radio via
the supplied DC power adapter.
WARNING: Do not exceed more
than 12A@120VAC or
6A@240VAC total current
connected to the DC adapter.
2.2.2 Ethernet Connection
The Trimar-AP connects to an
Ethernet port of a switch or hub
with the supplied blue cross-over
UTP cable. To connect to a router, a DSL or cable modem, or a computer, use the white
straight-through UTP cable supplied. Use the status-LED below as a guide to assure
that the correct type of Ethernet cable is used.
2.2.3 Status LED’s
Use the proper UTP cable to connect the 100/10BaseT port (which resembles an over-
sized telephone jack) on the Trimar-AP to the 100/10BaseT port of the network
equipment (router or switch). Power on the Trimar-AP, the LED’s on the front panel
should exhibit the following patterns:
LED Color Light Pattern
ON Red Steady ON or Blinking ON
RX Green Blinking ON, when communicating over the wireless port;
Steady OFF, when wireless connection is not present.
TX Red Blinking, when transmitting wireless data.
Steady OFF, when not transmitting data

LINK Yellow Blinking ON, when communicating over the Ethernet port;
Steady OFF, when Ethernet connection is not present.
If the yellow LED stays off, then the Ethernet connection to the Ethernet port is not
made. Check your UTP cable and make sure that the correct type (straight-through or
cross-over) of UTP cable is used. If one cannot communicate and the green LED is off,
you may want to re-position the Trimar-AP to a different location for better RF
transmission/reception. You may also want to check if the unit is configured with the
proper RF channel and security settings by using the Web-based Administration Utility.
Once the hardware is checked out to work properly with the network equipment, the
radio can be secured in the desired location by the pair of Velcro tabs.

Chapter 3: Operating Modes & Functional Features
In addition to performing standards-compliant AP functions, OTC Trimar-AP has many features
of convenience and it provides several modes of operation.
3.1 DHCP Client for Self
Dynamic Host Configuration Protocol client automatically gets IP address and DNS
addresses from the DHCP server. Wireless DHCP client can be configured to provide
host name to DHCP server for better management.
3.2 Wireless DHCP Server
Dynamic Host Configuration Protocol server that automatically assigns IP addresses to
wireless client stations logging onto a TCP/IP network. It eliminates having to manually
assign permanent IP addresses. DHCP server runs in Access Point and is capable of
assigning IP address only to wireless clients who is authorized to use the AP. DHCP
servers also dynamically update the DNS servers information when connected.
Source filtering
DHCP server will filter the request based upon source port, namely wireless, wired and
WDS.
3.3 WDS –Wireless Distribution System
Wireless Distribution System (WDS) allows packets to pass through without
modification from one wireless access point to another. This feature is especially
interesting to those who require transparent bridge because application only runs on a
wired Ethernet switch due to special network protocol it use. One throw back of using
this feature is one cannot use any of the stronger WPA authentication and encryption1.
Enable WDS -Enable or disable WDS.
WDS MAC -Up to 6 MAC addresses of adjacent WDS Access Point.
3.4 STP-Spanning Tree Protocol
Trimar-AP is equipped with STP. Spanning Tree Protocol is used in transparent
bridges to dynamically determine the best path from source to destination. It
avoids bridge loops (two or more paths linking one segment to another), which
can cause the bridges to send packets to wrong destination in infinite loop. This
protocol creates a hierarchical "tree" that "spans" the entire network including all
1IEEE802.11 Standards neglect to define how APs in WDS relationship would authenticate each other.

switches. It determines all redundant paths and makes only one of them active at
any given time. The spanning tree protocol (STP) is part of the IEEE 802.1
standard. New STP will be capable of informing network topology change to the
transparent bridge causing forwarding table to be refreshed.
Enable STP -Enable or disable STP feature.
3.5 Transparent Bridge
New transparent bridge will use unique MAC address for Ethernet port to fully
utilize Spanning Tree Protocol’s capabilities. In the past most of wireless Access
Point use wireless radio’s MAC address as Ethernet MAC address causing STP
to misinterpret the forwarding path.
Use Ethernet MAC address -Flag transparent bridge to use separate Ethernet
MAC address
MAC address -Ethernet MAC address to use if value is none-zero. If the value is
all zeros then use burned in unique MAC address.
3.6 WDS Configurations
To Enable WDS feature, click on the Enable WDS check box and enter MAC address of
adjoining WDS unit (AP2). Then repeat the same procedure from the adjoining WDS
unit but enter MAC address of initial WDS unit (AP1). Two linked WDS units should
have MAC address pointing to each other’s unit. Also, linked WDS units must share
same wireless channel. This can be accomplished from the “Wireless” Web page
Channel selection option. When WDS radio sees adjoining WDS unit, INFO Web page
should display neighboring WDS information.
